Definitions

  • the invention relates to an arrangement according to the preamble of claim 1.
  • a measuring arrangement is known from vehicles in US-A-4,630,470. At the individual wheels are artificially stimulated to vibrate, of which a frequency spectrum is recorded. Through a A comparison of the spectra of the individual wheels with each other is intended Wheel whose pressure differs from that of the other is recognized are at a changed frequency spectrum. This arrangement assumes that the majority of the wheels of a vehicle with the correct tire pressure is provided; otherwise wheels are included Underpressure or overpressure not recognizable.
  • the invention is therefore based on the object of a measuring arrangement to create the exact tire footprint to determine with the isobars of each wheel, to represent them arithmetically and to compare with those of the other bikes. For the vehicle speed must perform this measurement and calculation process and a large number per wheel, e.g. at least 10 rollover segments recorded become.
  • the data acquisition system stores the individual tire contact patches immediately between and compares special features of the isobar course with the imprint images of the other wheels of a vehicle.
  • the isobar images of heavy traffic the biggest road damage and in general also caused the most serious accidents regardless of the vehicle and / or Tire brand as well as of the vehicle or tire type, very much
  • the isobaric images can be similar and comparable also with the image of one stored in the data acquisition system "Normal pressure" isobars for the respective vehicle type be compared, for example, from the same time recorded axle load and / or the number of rolling over the system Wheels or axles can be closed.
  • a pictorial representation or an elimination signal are immediate available after crossing, processing speed must be so high that vehicles with faulty tire pressures can be eliminated from normal road traffic; this is how traffic is monitored according to tire pressure conditions possible.
  • FIG. 1 shows a measuring rail 12 according to the invention with a Row arrangement of force measuring elements 1,2,3..n, shown, whose width with B and their length, viewed in the direction of travel R, are denoted by L.
  • Each force measuring element 1,2,3 has its own Crystal arrangement 5 provided as a sensor, which upon exposure a force F a proportional electrical signal into a Outputs signal line 6.
  • the individual Cell 1, 2, 3 are saw sections of a metal profile, consisting of force inlet flange, pipe part 11 and Force support flange.
  • the crystal arrangement 5 is in the tube part 11 housed under mechanical preload in a plastic spout 9.
  • the single force measuring elements 1,2,3 .. are with a sand-epoxy infusion plate 10, the total after Installation can be ground with the street surface.
  • the Spaces S between the individual force measuring elements 1,2,3 kept as small as possible and cast with polyurethane casting resin.
  • the total length of a measuring rail 12 can e.g. 1 m or more be; it has a width B of a single element of 20 mm about 50 and more force measuring elements 1,2,3 on the mounting rail 8 are mounted.
  • the fully assembled measuring rail 12 is installed still with side pad 15, consisting of casting compound and rubber band 16 provided and then in the prepared street groove 17 with Casting compound 18 cast.
  • the dimensions of the street groove 17 with respect to depth T and width W according to the invention are approximately 1: 1, which means that a solid anchoring is guaranteed even with rolling traffic becomes.
  • the upper part E of the measuring rail 12 represents the force introduction part, the middle M the signal conversion part and V the anchoring part
  • the surface part O is made by grinding into a flat surface brought to the street surface.
  • the tire 19 is in the making to drive onto the measuring rail 12.
  • the rollover process of the tire 19 results in a rollover signal Si 1 , Si 2 , Si 3 ... in each individual force measuring element 1 , 2 , 3 , proportional to the force F over time t.
  • These rollover signals and the vehicle speed v form the main parameters of the subsequent computer work in the data acquisition system.
  • Fig. 3 shows the tire 19 in elevation just above the built-in Measuring bar 12.
  • FIG. 4 shows FIG. 3 in plan view above the measuring rail 12.
  • the tire contact area 20 is usually wider than the tire width b 1 .
  • the measuring rail 12 with the individual force measuring elements 1, 2, 3 and their width B divides the tire contact area 20 into at least 8 to 10 subsections 21, which enables a satisfactory resolution of the subsequent computing power.
  • FIG. 5 shows the measuring rail 12 in plan with the individual force measuring elements 1, 2, 3, superimposed by an average tire profile 22, shown in the direction of travel R.
  • at least three partial areas T f1 , T f2 , T f3 of the tire profile 22 on one Individual force measuring element 1, 2, 3 rests, their lengths L should be at least about 50 mm.
  • the data calculated in this way can be used to assess the tire pressure different evaluation methods can be selected.
  • an appropriate Programming of data acquisition can be done, for example Absolute values of the respective tire pressure from the with With the help of the previously laid contact rail certain vehicle speed and the lengths lx of the recorded tire contact patches determine.
  • Fig. 8 shows a rear axle of a truck with two double tires each each via measuring rails 12.
  • FIG. 9 shows the peak values of the tires shown in FIG. 8 when the measuring rails 12 roll over.
  • the maximum values of the individual roll signals Si 1 , Si 2 , Si 3 which are the sum curves 46 for negative pressure, 45 for normal pressure and 47, are sufficient result for overpressure and can be easily recognized by calculation. From the surfaces of curves 45 to 47, the axle loads, separated on the left and right, can be calculated immediately by the computer.
  • Fig. 10 shows in the application example where a truck 50 in a Petrol station drives in. After reaching the tap 51 is on the display panel 52 contains the information of the measuring rail 12 that has been rolled over and the contact rail K, which is let in a few meters ahead displayed.
  • Fig. 11 shows the floor plan where the measuring rail 12 in the middle of the lane divided and based on the direction of travel 12 l of the left Half of the lane and 12 r assigned to the right half of the lane is; this in turn enables the tire conditions to be recorded at the same time, as well as the summation of the axle weights of the left and right vehicle halves.
  • any overweights as well as the load distribution can be checked immediately. So that results an interesting additional range of services the petrol station owner. Similarly valuable, automated data can become important at truck terminals.
  • the arrangement according to the invention can thus make important contributions to Bring increased operational safety in vehicle traffic by inadmissible tire pressure conditions recognizable in rolling traffic and be made separable.
  • the invention also enables automated additional security check in vehicle terminals or at taps.
